GAS-PRODUCER.

Specification of Letters Patent.

Patented Jan. 9, 1912.

To all fwho/rn it may concern:

Be it known that I, CLAUDE M. GARLAND, a citizen of the United States of America, and resident of Collingswood, in the county of Camden and State of New Jersey, have invented certain new and useful-Improvements in Gras-Producers, of which the following is a specification.

The objects of my invention are to construct a gas producer which will generate in a simple manner, from bituminous coal and other fuels rich involatile matters, gas practically free from tar and other objec tionable, condensable hydro-carbons; to be able to eiiiciently convert the ta-r intoa permanent gas; to provide a compound gas producer, which is capable of continuous operation, and to gain eiiiciency of production and simplicity of operation.

Figure 1 is ageneral sectional elevation, some parts however being external views, and some parts broken away to permit the essential elements to be drawn to as large a scale as possible. Fig. 2 is a sectional view of a detail.

The organization'compri'ses an upper generating chamber A, supported upon beams A1. Below the chamber A, is a lower chamber B. K'is the shell of the chamber A,

which shell is lined on the inside with fire bricks K1, and finished at the top by a steam jacket D, for the passage of the blast of air and steam onv its way to the interior of the chamber A from the twyers 27 and through the portY D1. The fuel charging hopper C terminates al the port D. One of the poke holes isA at E, provided through the walls of the jacket D. f

At the bottom of the chamber A, is an annular opening for the discharge oi permanent gas, volatile products and partially gasified fuel. This opening is formed in the following manner: The 4lower end of the chamber A is inwardly conical downward, and, projecting into the lower open' end of the chamber A is a structure K10 being conically pointed upward and small enough to leave the annular discharge opening between itself and thev lower edge of the chamber A. F is a water cooled mantle for supporting the re brick lining K1, and

ywhich is riveted to the conical shell G, which =in turn is rigidly secured to the main shell K. The beams H support a cast iron plate' tI, spaced from the lower edge of the chamber A and supporting the fire brick structure K10 so as to form a combination of the 1 annular opening above mentioned. casing or shell K projects cylindrically downward, and opposite the conical portion The G, thereby leaving a space between this projection and the conical portion Gr. In this space is a ball race L, provided with balls Rigidly mounted upon the upper cover @N of the ball race L, is a rotary annular rack O. Engaging with the rack is a bodily :stationary but rotating pinion Q, turned by lmeans of gearing R and crank T. When the rack is rotated onits axis, by means of the crank T, the poker U revolves around 1 and in the discharge opening, yfor the poker is carriedon a bracket P, which is attached 5to a rotating cover N, and rack O.

V is an annular water jacket provided with an inlet pipe V1, and overlow pipe V2. This water-jacket V is attached to the inner surface of the shell K in the space 30 opposite the conical portion G.

Y represents cleaning doors locatedv around the lower part of the shell K.

K2 is a funnel forming a` continuation of the chamber A and ending in a pipe W', which communicates with thev top of the lower gas generating chamber B, which latter is provided with a charging hopper Z,

`conveniently extended through the wall of the pipe W. The gas oil-take pipe for the chamber B is 3. Connecting this pipe and the pipe WV is a third pipe l having a valve 2. The chamber B may be cut oli? from the generator A by a valve X in the pipe WV, and by the valve 2 in the pipe l.

4; is a valve in the pipe 3 for cutting oli `communication between the chamber B and the pipe 1. Supporting the fire brick lining is a mantle ring 8, riveted and bracketed to 15. The space 28, permits the easy removal of ash. The water space 6 is provided with gage glass 16, back pressure valve 17, water inlet pipe 18 and steam discharge 19. Extending through the water space is the poke hole casting 20. The steam pipe 19 leads toW the air inlet pipes 21 and 22, which are provided with regulating valves 2? andY 24. The steam pipe isprovided with regulating valves 25 and 26.

' The operation of the compound producer is as follows: Assume that the valves X and 4 are open and the valve 2 closed. Fuel is discharged into the chamberv A through the hopper C. Air, forced from a blower or through induction, and steam, for t-he gasication `of the fuel enter the twyers 27, circulate through the top plate D, cooling the same, and pass down through, and gasify a portion of the fuel. The gases formed, pass out through the space 29, and down through the pipe W into the chamber B, and out through t-he pipe 3. From time to time, the operator revolves the crank T, which rotates the annular rack O and cover N, to which is bracketed the poker U.. The rotation of this poker pushes the partially gasiiied fuel from the plate I, and this falls into the chamber B, where theblast of air and steam from the hood 14, completes the gasification. The poker U may be rotated continuously by power instead of by hand. The sensible heat from the gases and from the fuel in the chamber B generates steam in the jacket 6, the steam beingheld under a constant pressure by the back pressure valve 17, and allowed to pass through the regulating valves 25 and 26, in quantity depending upon the requirements of the fuel and mixes with the air forming the blastfor the producer. The airV may be supplied to the producer at a pressure greater than atmospheric pressure, or it vmay be induced through the producer at a pressure lower than atmosphericpressure. The conical firebrick structure K10 1s used to facilitate the even descent of the fuel in the chamber A. VThe water jacket at V' supp-lies steam within the space 30' which steam keeps down the temperature of the working parts inclosed within the shell orv casing K. The valves X, 2 and 4 are used in casesof emergency to isolate either generating chamber without eii'ecting the opconvert If the chamber B were to be 4shut down, thev valves'X and 4 would'be closed and the valve 2 opened. v

By means of this invention, I am able to the condensable hydrocarbons evolved during the process of gasification, l

into Vvpermanent combustible and useful ,'gases, thereby avoiding any necessity of eX- fpensive scrubbing apparatus and loss of time and labor, while at the same time, increasing the efficiency of the process.

I claim as my invention v 1. In a gas producer, the combination o coaXially superimposed gas generating chambers, a fuel charging device centrally located at the top of each chamber, twyers at the top of the upper chamber and at the bottom of the lower chamber respectively, a pipe for the passage of gas and partially gasiied fuel communicating from the center of the bottom of theupper chamber to the center of the to of the lower chamber, and a gas Gif-take pipe communicating with the upper portion of the lower chamber.

2. In a gas producer, the combination of superimposed gas generating chambers, a pipe communicating from the bottom of the upper chamber to the topof the lower chamber for the passage of both gas and partially' gasiiied fuel, a valve in said pipe, a gas off-take pipe leading from the gas space'inthe upper part of the lower chamber, a valveV in the gas oE-take pipe, a oonnecting pipeleading from the iirst named pipe at aV point above said valve therein, to the gas oif-take'pipe and located on the other side of the valve therein from said lower chamber, and a valve in said connecting pipe. y Y

3. In a gas producer the combination of superimposed gas generating gasified fuel from the bottom of the upper chamber to the gas space at the top of the lower chamber, a gas off-take pipe located at the upper portion of the lower chamber and communicating with the gas -space therein, means for cutting off communication between the two chambers, and a gas (iE-take pipe communicating with the space labove said means and below said chamber.
